Hi there everyone.  
Just kicking off this topic to discuss specific examples of real world film scanners.

My hope is that everyone can discuss their ideas regarding any specific part of the Kinograph in relation to real world examples. For example, film transport tension. Let’s discuss the DIY approach but in regards to known and current scanning transport technologies.  
If we can replicate a proven technology or enhance using the DIY approach we may save a lot of reinventing the wheel so to speak.

Here is a YouTube clip showing the Walde scanner. This is a good overview of a quality scanner.

Great new topic. Love the idea of taking the best from the best and simplifying.

Thank you. You actually simplified everything I said above in one sentence.

@anthony this video is amazing. Thanks so much for posting a lot to dig into.

1. Film Path = 3x roller at each reel to feed tension arms. 2x roller at gate for pre-scan camera setup.

2. Gate - curved (using linear scan camera), swaps out with screws

3. Overall orientation - reel over reel. easy to understand and access all parts of film path.

4. Alt path for PTRs.

5. Imaging - pre-scan camera takes care of frame detection + more

6. Software - simple, straightforward interface focused on capture only

7. Capstan - this drives the machine - but how and how is it designed?! Would love to see that upclose.

Not pictured or defined = motors. Argh. Go go gadget x-ray vision!
